There are approximately 560,000,000,000 planets in outer space that scientists have discovered. In this solar system, there are eight planets. In this galaxy, there are likely between 50 billion and a trillion planets-or more. At this point, we can hardly guess.
Officially, there are 8 planets in solar system: 4 of them are terrestrial (Mercury, Venus, Earth and Mars) and 4 are gas giants (Jupiter, Saturn, Uranus, and Neptune). There is no such a planet that is not either a gas giant or a terrestrial planet. Pluto is not considered a planet any more, but an icy dwarf, as opposite to Ceres, which is terrestrial dwarf.
